Authorities say a worker performing maintenance on a metal-cutting machine in Gardena has died after the machine was switched in with him inside.
The Daily Breeze of Torrance says the man was dead when emergency crews arrived Monday at the business south of Los Angeles.
The man was working on a machine that cuts aluminum and sheet metal.
His name wasn't released but police say he was in his 50s and had worked at the business for about a year.
